Q. A sanding disk with rotational inertia 5.4 x 10-3 kg·m2 is attached to an electric drill whose motor delivers a torque of magnitude 10 N·m about the central axis of the disk. About that axis and with torque applied for 72 ms, what is the magnitude of the (a) angular momentum and (b) angular velocity of the disk?

Q. How many time constants must elapse for initially uncharged capacitor in RC circuit to be charged 99% of its equilibrium state?
